Use of CO2 (carbon dioxide) gas sensors in food processing extends the storage and usable shelf life of both fresh and shelf stable food products. In meat processing, CO2 gas sensors assist in retaining the natural meat color and inhibits bacterial growth.

The most common reason for use of CO2 gas sensors is to exclude oxygen (O2) from the atmosphere contained inside the storage packaging. When oxygen levels can be dropped below 2.0%, the amount of deleterious oxidation reactions in stored foods can be greatly decreased resulting in longer palatability and nutritional shelf live.

A less common, but very important use for CO2 gas sensors is fumigation. This is the killing or retarding of insect life contained in the food product.
